The web_image() function

Get the PNG-based logo for the R Project from an image URL.

r_png_url <- "https://www.r-project.org/logo/Rlogo.png"

Create a tibble that contains heights of an image in pixels (one column as a string, the other as numerical values), then, create a gt table. Use text_transform() to insert the R logo PNG image with the various sizes.

dplyr::tibble(
  pixels = px(seq(10, 35, 5)),
  image = seq(10, 35, 5)
) |>
  gt() |>
  text_transform(
    locations = cells_body(columns = image),
    fn = function(x) {
      web_image(
        url = r_png_url,
        height = as.numeric(x)
      )
    }
  )

Get the SVG-based logo for the R Project from an image URL.

r_svg_url <- "https://www.r-project.org/logo/Rlogo.svg"

Create a tibble that contains heights of an image in pixels (one column as a string, the other as numerical values), then, create a gt table. Use tab_header() to insert the R logo SVG image once in the title and five times in the subtitle.

dplyr::tibble(
  pixels = px(seq(10, 35, 5)),
  image = seq(10, 35, 5)
) |>
  gt() |>
  tab_header(
    title = html(
      "<strong>R Logo</strong>",
      web_image(
        url = r_svg_url,
        height = px(50)
      )
    ),
    subtitle = html(
      web_image(
        url = r_svg_url,
        height = px(12)
      ) |>
        rep(5)
    )
  )
